Perennial seeds require a wintering period for germination. Place them in the refrigerator for 60 days before sowing in spring. Sow in trays, making sure the seeds are lightly covered. When plants have 5-6 leaves, transplant into individual pots or directly into warmed soil, 1 m apart in all directions. Autumn sowing is done in the same way and left outdoors until spring.
